Description

Technical Field

[0001] This utility model relates to the field of installation technology of PTC thin film cooling devices, and in particular to a high-efficiency PTC thin film cooling device that is easy to install. Background Technology

[0002] In industrial production, PTC films are widely used in electronic devices, heating elements, and many other fields due to their unique electrical properties. However, PTC films generate a large amount of heat during operation. If this heat cannot be dissipated effectively and in a timely manner, it will seriously affect their performance and service life, and may even cause safety hazards. Therefore, an efficient cooling device is crucial for the stable operation of PTC films.

[0003] Traditional PTC thin-film cooling devices are typically installed using bolts. While this method offers some stability, it has several drawbacks in practical use. Firstly, disassembly and assembly require specialized tools, making the process cumbersome and demanding a high level of skill from operators. Secondly, each maintenance or replacement of the cooling device requires significant time for bolt removal and installation, often exceeding 30 minutes. This not only increases maintenance costs but also disrupts the continuity of the entire production line, leading to reduced production efficiency. Therefore, we propose an easy-to-install, high-efficiency PTC thin-film cooling device to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an easy-to-install, high-efficiency PTC thin-film cooling device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A PTC thin-film high-efficiency cooling device that is easy to install includes a support plate. An L-shaped fastener is fixed to one side of the upper end of the support plate.

[0011] Preferably, two connecting blocks are fixed on both sides of the support plate, and the connecting blocks are provided with mounting holes.

[0012] In this invention, when cooling the PTC thin film:

[0013] 1. Initial installation and positioning: Place the carrier plate on the top of the PTC film. The connecting blocks on both sides of the carrier plate are provided with mounting holes. The carrier plate can be fixed in the corresponding position through the mounting holes, providing a stable support foundation for the subsequent installation of the cooling fan body.

[0015] 3. Connection between trapezoidal insert and fixing block: The cooling fan body is connected to the mounting block via studs. The trapezoidal insert on one side of the mounting block engages with the trapezoidal slot on the fixing block on the L-shaped fixing component side. Before engagement, the mounting block can be rotated to move the stud within the threaded blind hole on one side of the mounting block, further adjusting the position of the cooling fan body and improving the tightness of the engagement.

[0016] 4. Limiting mechanism fixation: Insert the U-shaped plug through one side of the support block into the two through holes and the fixing block on one side of the trapezoidal plug. A rubber sleeve is fitted on the side wall of the U-shaped plug to enhance the stability of the connection. By inserting the U-shaped plug, the final fixation of the cooling fan body and the support plate is completed.

[0017] This utility model has the following advantages:

[0018] 1. Compared with the traditional bolt fixing method, this device adopts the snap-fit ​​and plug-in installation method. No special tools are required. Operators can quickly complete the installation of the cooling fan body by simply plugging and inserting the parts, which greatly shortens the installation time and improves the installation efficiency.

[0019] 2. When maintaining or replacing the cooling fan body, no complicated tools or operations are required. Simply pull out the U-shaped plug to easily disassemble the cooling fan body, reducing the time and labor costs required for maintenance and lowering the maintenance costs throughout the production process.

[0020] 3. The snap-fit ​​method between the trapezoidal plug and the trapezoidal slot, as well as the limiting function of the U-shaped plug rod, makes the cooling fan body more stable during operation, effectively avoiding noise and vibration caused by fan shaking, and ensuring the stability of the cooling effect.

[0021] In summary, this utility model adopts a snap-fit ​​and plug-in installation method, which eliminates the need for special tools. Operators can quickly complete the installation of the cooling fan body by simply plugging and inserting the components, greatly shortening the installation time, improving installation efficiency, reducing the time and labor costs required for maintenance, lowering the maintenance costs in the entire production process, and making the cooling fan body more stable during operation. This effectively avoids noise and vibration caused by fan shaking and ensures the stability of the cooling effect. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figure 1-4 A PTC thin film high-efficiency cooling device that is easy to install includes a support plate 2. An L-shaped fastener 9 is fixed on one side of the upper end of the support plate 2. The design of the L-shaped fastener 9 not only serves to connect and support, but also provides suitable space and angle for the installation of other components. Its material is high-strength aluminum alloy, which ensures that it will not deform during long-term use, thereby ensuring the stability of the entire device.

[0029] A fixing block 14 is fixed to one side of the L-shaped fastener 9. A trapezoidal insert 6 is snapped into one side of the fixing block 14. An mounting block 5 is fixed to one side of the trapezoidal insert 6. A stud 4 is threaded onto one end of the mounting block 5. A cooling fan body 1 is fixed to one end of the stud 4. The cooling fan body 1 is composed of four DC cooling fans with a speed range of 600-2000 RPM and a maximum air volume of 71.6 CFM.

[0030] The lower end of the cooling fan body 1 is snapped onto one side of the support plate 2. The support block 7 is fixed on one side of the fixing block 14. A limiting mechanism is provided through the support block 7. The limiting mechanism is snapped onto the trapezoidal plug 6. The trapezoidal structure design of the trapezoidal plug 6 enables automatic alignment during the snapping process. Furthermore, when subjected to external force, the interaction between the trapezoidal surfaces can effectively prevent the plug from coming out, thus improving the reliability of the connection.

[0031] A trapezoidal slot 13 is provided on one side of the fixing block 14, and the trapezoidal insert 6 is engaged in the trapezoidal slot 13. The limiting mechanism includes a U-shaped insert 8 that is provided through one side of the bearing block 7. Two through holes 16 are provided on one side of the trapezoidal insert 6. One end of the U-shaped insert 8 passes through the fixing block 14 and the two through holes 16. A rubber sleeve is provided on the side wall of the U-shaped insert 8. The rubber sleeve can increase the friction between the U-shaped insert 8 and the through holes 16 and prevent the U-shaped insert 8 from loosening.

[0032] One side of the mounting block 5 is provided with a threaded blind hole. One end of the stud 4 is threaded into the threaded blind hole. The thread accuracy of the threaded blind hole and the stud 4 meets the standard, ensuring precise control when adjusting the position. When rotating the mounting block 5 to adjust the position, use a wrench to avoid excessive force that could damage the stud 4 or the threaded blind hole. When engaging the trapezoidal insert 6 and the trapezoidal slot 13, apply a small amount of lubricating oil to the slot to reduce friction during engagement and make the engagement process smoother.

[0033] The upper end of the support plate 2 is provided with four conveying holes 12. The lower end of the cooling fan body 1 passes through the conveying holes 12. A plug plate 15 is fixed on one side of the lower end of the cooling fan body 1. A slot 11 is provided on one side of the upper end of the support plate 2. One plug plate 15 on the same side is inserted into one slot 11 on the same side. The size and shape of the conveying holes 12 are precisely designed according to the lower end size of the cooling fan body 1 to ensure that the cooling fan body 1 can pass through smoothly. At the same time, the fit gap between the plug plate 15 and the slot 11 should be moderate. It should not be too loose to cause the fan to shake, nor too tight to affect the installation.

[0034] Two connecting blocks 3 are fixed on both sides of the bearing plate 2. The connecting blocks 3 are provided with mounting holes 10. When inserting the U-shaped plug 8, it is necessary to ensure that it is fully inserted and that the rubber sleeve is tightly fitted between the U-shaped plug 8 and the through hole 16.

[0035] In this invention, when cooling the PTC thin film:

[0036] 1. Initial installation and positioning: Place the carrier plate 2 on the top of the PTC film. The connecting blocks 3 on both sides of the carrier plate 2 are provided with mounting holes 10. The carrier plate 2 can be fixed in the corresponding position through the mounting holes 10, providing a stable support foundation for the subsequent installation of the cooling fan body 1.

[0037] 2. Initial installation of the cooling fan body: Align the lower end of the cooling fan body 1 with the delivery hole 12 on the carrier plate 2 and insert it into the delivery hole 12. At the same time, the insertion plate 15 on the lower side of the cooling fan body 1 will be inserted into the slot 11 on the upper side of the carrier plate 2, thus realizing the initial positioning and initial fixation of the cooling fan body 1 on the carrier plate 2 and ensuring the accuracy of the fan position.

[0038] 3. Connection between trapezoidal insert and fixing block: The cooling fan body 1 is connected to the mounting block 5 through stud 4. The trapezoidal insert 6 on one side of the mounting block 5 is engaged with the trapezoidal slot 13 on the fixing block 14 on one side of the L-shaped fixing part 9. Before engagement, the mounting block 5 can be rotated to move the stud 4 in the threaded blind hole on one side of the mounting block 5 to further adjust the position of the cooling fan body 1 and improve the tightness of engagement.

[0039] 4. Fixing the limiting mechanism: Insert the U-shaped plug 8 through one side of the bearing block 7 into the two through holes 16 and the fixing block 14 on one side of the trapezoidal plug 6. A rubber sleeve is fitted on the side wall of the U-shaped plug 8 to enhance the stability of the connection. By inserting the U-shaped plug 8, the final fixing of the cooling fan body 1 and the bearing plate 2 is completed.

[0040] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto.
